There are animals on our planet that have been living quietly for hundreds of years. These include sea creatures, reptiles, birds, fishes, and animals. Listed below are some. Take a look.
Red sea urchins
Sea Urchins are known to live an average of about 200 years. These invertebrates live in shallow water off the west coast of America. The sea urchin, passing through all stages of development to an adult in just 1 month, at the age of two years reaches a size of 4 cm, and then annually adds 10 millimeters in height. These animals attracted the special attention of scientists after a mark dated 1805 was found on one of the living individuals.
Bowhead whales
These bowhead whales can live up to 200 years. The average lifespan of this species is about 40 years. However, some can live up to 211 years, which is a record among vertebrates. 103-year-old the oldest known killer whale is the matriarch of a community of killer whales known as J-Pod. Killer whales give their first offspring at the age of 14 and stop giving birth at the age of 40. The offspring live with their parents all their lives, and it was this factor that made it possible to determine the age of the Granny killer whale.
Giant tortoise
Another long-liver among the representatives of turtles is the 250-year-old Advaita, a giant tortoise from the island of Aldabra, who died in 2006. The average weight of such a turtle is about 120 kilograms. Advaita was very popular with tourists and attracted many visitors to the Calcutta City Zoo.
Immortal jellyfish
These creatures live in the Mediterranean Sea and in the waters of Japan. Their amazing ability to live forever was discovered by accident by student Christian Sommer in 1988. These jellyfish don’t die. And In other words, they grow in reverse, getting younger and younger until they reach an early stage of development where they started their life cycle all over again. Later, scientists from Genoa, who deepened the research in 1996, published Reversing the Life Cycle, which described the transformation of adults back into polyps, which, in fact, opens the way for these creatures to potential immortality. They are also called Benjamin Button’s jellyfish.
Hoplostet
It is a species of deep-sea fish that reaches sexual maturity after 20 years and can live up to 150 years. This means that the oldest known hoplostet was born around the same year when Abraham Lincoln was president of the United States.
